swissTLM3D

swissTLM3D is the large-scale topographic landscape model of Switzerland. It includes both natural and artificial landscape features, as well as name data in vector form. With a high degree of accuracy and the incorporation of a third dimension, swissTLM3D is the most extensive and accurate 3D vector dataset of Switzerland.

The large-scale topographic landscape model of Switzerland

Version 2.3

swissTLM^3D is available for all of Switzerland and the Principality of Liechtenstein. The current release has the version name swissTLM^3D 2.3. A PDF document containing a full overview of the swissTLM^3D 2.3 data catalogue, including a list of modifications made in comparison to swissTLM^3D 2.2, is available in German or French.

Applications

swissTLM^3D can be used for a wide range of applications thanks to its simple and clearly defined landscape feature structure:

• as a reference data set for establishing information systems (e.g. dynamic segmentation based on the road network of swissTLM^3D)
• as a basis for 3D visualisations and analyses (depending on the application, in conjunction with swissALTI^3D)
• as a database for simulations, plans and statistics
• as a starting point for publications (maps, plans, Internet) and finished products (e.g. multimedia, navigation or geomarketing)

  Structure

  swissTLM^3D describes more than 21 million landscape features, together with their position and shape, the corresponding landscape feature type and many other attributes. swissTLM^3D comprises of 8 topics, each of which contains one or more feature classes.

  Roads and tracks: Different road and track categories

  
  Public transport: Railway lines and other rail systems, shipping routes and public transport stops

  
  Buildings: Buildings, walls, dams, constructions relating to transport, communication, energy, sport and leisure

  
  Areas: Plots with special land usage (transport, nature, habitat, leisure, etc.)

  
  Land cover: Ground coverage independent from land usage

  
  Hydrography: Watercourses and lake contours

  
  Single point objects: Selection of prominent landscape features which aid orientation (crossings, sources, caves)

  
  Names: Various names (mountains, areas, towns, etc.)

  File formats

  swissTLM^3D is available in the following file formats:

  • ESRI File Geodatabase
  • ESRI Shapefile
  • GeoPackage
  • DXF (please order data by email at [e-mail])

  Quality

  Geometric accuracy:

  •  For well-defined landscape features such as roads or buildings: 0.2 to 1.5 m in all three dimensions
  • for landscape features which are not clearly defined (e.g. forests): 1 to 3 m in all three dimensions
